Help with Twitter, arduino and Ethernet Shield

Hi guys, Thanks for checking this post out, I am a uni student in need of help!

I have an Arduino Uno, and Ethernet shield and a computer (obviously) and I would like to search Twitter for and @user followed by a #hashtag to then control my arduino.

My idea is that a user would post @arduinoproject #DoThis and the Arduino (or my comuputer) would pick this up then triggering the funtion.

How would I do this? (getting the Arduino, using an ethernet shield, to react to a command on Twitter)

Thanks so Much!

Clive

I've already done that search and no one seems to be in my position. ...

i'm having partly the same question and have googled it etc but can't seem to find what i need, which i think thousands of people must have used already before: i want my arduino to react to hashtags all over twitter (and/or other hashtag using sites as instagram and tumblr), not just something from my twitter account alone. does anyone have good tips or a link on where to find something like this? cheers!

Perhaps what you think is not correct.

I would have thought the natural way to deal with that problem was to create a mashup on the PC that sent commands directly to the Arduino to do stuff as required. Trying to do the web collection and parsing on the Arduino seems like a much less promising direction to try.
